Newcastle housing profile

Originally a coal-mining area like Renton, Newcastle's residential development concentrates in the 1960s-70s Newport Hills planned community plus 1990s+ Coal Creek and Newcastle Hills construction. The hillside terrain puts these homes on concrete slabs rather than crawlspaces.

Common plumbing issues in Newcastle

  • 1960s-70s slab leaks in Newport Hills copper supply. Under-slab copper from the original Newport Hills construction era is in the slab-leak failure window.
  • Galvanized service lines from 1960s development. Original Newport Hills construction used galvanized; now 60+ years old and failing.
  • Hillside sewer line bellies and root intrusion. Sloped lots plus mature trees produce consistent sewer issues.
  • Stormwater drainage in low-lying May Valley properties. May Valley drainage during heavy rain affects basement and crawlspace plumbing.

About working in Newcastle

Newport Hills, the largest Newcastle neighborhood, was developed during 1965-1975 as a planned hillside community. The under-slab copper supply lines from that era are now in their 30-40 year slab-leak failure window — and the earliest Newport Hills lines are 50+ years old. Acoustic and thermal-imaging leak detection is essential equipment here. The 1960s construction also includes original galvanized service lines from meter to house that are now well past service life. We run equal volumes of slab leak detection and water service line replacement (trenchless PEX-A) in Newport Hills.
